#1
Work done is given by
here we know that
F = 157 N
d = 14.5
now from the above formula
#2
By energy conservation
Initial total potential energy of egg = final total kinetic energy of egg
#3
By momentum conservation we know that
#4
by momentum conservation we know that
let direction of velocity of Jay Z car motion is positive direction
now we will say
Yes Jay Z is overspeeding as his speed is more than speed limit
#5
Tension force in the string will be centripetal force
so here we can say
here we know that
m = 0.63 kg
v = 7.8 m/s
R = 0.23 m
Proton I think if I remember right
Answer and Explanation:
The hydrogen atom is an atom of hydrogen element.Hydrogen atoms contain one proton which has positive charge and one electron which has negative charge , so due to positive and negative charge present in the hydrogen atom its becomes neutral atom.In whole universe the hydrogen atom is found in most abundant. Electron and nucleus of the hydrogen atom is bound together with the help of coulomb force.
A) 
The magnitude of the capacitive reactance is given by
where
is the angular frequency
C is the capacitance
While the magnitude of the inductive capacitance is given by
where L is the inductance.
Since we want the two reactances to be equal, we have
So we find
B) 7449 rad/s
In this case, we have
is the inductance
is the capacitance
Therefore, substituting in the formula for the angular frequency, we find
C) 
Now we can us the formulas of the reactances written in part A). We have:
- Capacitive reactance:
- Inductive reactance:
Answer:
g ≈ 2.82 m/s^2
Explanation:
By W = mg,
W = weight (in newtons)
m = mass (in kg)
g = gravitational acceleration (in m/s^2)
g ≈ 2.82 m/s^2
